Title (EN) MULTICOMPONENT VISCOELASTIC SURFACTANT FLUID AND METHOD OF USING AS A FRACTURING FLUID
(FR) FLUIDE TENSIOACTIF VISCOELASTIQUE A COMPOSANTS MULTIPLES ET SON PROCEDE D'UTILISATION COMME UN FLUIDE DE FRACTURATION
Abstract: front page image
(EN)There is a viscoelastic fluid. The fluid has one or more cationic surfactants selected from the group consisting of certain quaternary salts, certain amines, and combinations thereof; one or more anionic polymers/anionic surfactants; one or more of certain zwitterionic/amphoteric surfactants; and water. There is also a method of fracturing a subterranean formation. The viscoelastic fluid is pumped through a wellbore and into a subterranean formation at a pressure sufficient to fracture the formation.
(FR)La présente invention a trait à un fluide viscoélastique, comportant un ou des tensioactifs cationiques choisis parmi le groupe constitué de certains sels quaternaires, certaines amines, et des combinaisons de ceux-ci; un ou des tensioactifs anioniques polymères/anioniques; un ou plusieurs parmi certains tensioactifs zwitterioniques/amphotères, et de l'eau. L'invention a également trait à un procédé de fracturation d'une formation souterraine par le pompage du fluide viscoélastique à travers le puits de forage et dans la formation souterraine à une pression suffisante pour la fracturation de la formation.
